Product Description
Benefits/Features
• Gauge taps at the suction and discharge connections for complete monitoring flexibility
• Annular pressure reducing clearance with impeller balance holes to reduce axial thrust
• Precision-cast, dynamically balanced impeller minimizes vibration and maximizes bearing life
• Precision bearings and shaft design limit deflection at the seal face
• Standard case wear ring
• Mechanical seal is standard in carbon vs. silicon carbide (optional: tungsten carbide) with an external seal flush line
• Every pump hydrostatically pressure-tested
• Optional 250-lb discharge flanges on many models
• Standard construction with bronze shaft sleeve and steel shaft; optional stainless steel sleeve and shaft available
• Optional rigid mounting base
